Install:

sudo apt-get install vnstat vnstati

vnstat is meant to be used by any user so give correct permissions:

sudo chmod o+x /usr/bin/vnstat

sudo chmod o+wx /var/lib/vnstat/

Check available interfaces and add monitor service for one of them:

ifconfig

sudo vnstat -u -i eth0

sudo chown vnstat:vnstat -R /var/lib/vnstat

Check that it is working:

sudo service vnstat status

Now you can see network stats:

vnstat

vnstat -i eth0

vnstat -h -i eth0

vnstat -d -i eth0

vnstat -w -i eth0

vnstat -m -i eth0

For the live mode:

vnstat -l eth0
